Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed August 15, 1904. Serial No. 220,769.

To all whom it may concern:

Be it known that I, GUsTAvn L. lines, a subject of the Em eror ofAustriadl'ungary, and a resident of t 16 borough of Manhattan, in thecity and State of New York, have invented a new and useful Improvementin Terminal Tips for Electric ConductinglViros, of which the followingis a specification.

The object of my invention is to provide a terminal tip for wires--such,for instance, as electric oonduotin '-wires--which will he ex tremelystrong ant durable and which is particular y applicable 1" or use inconnection with the wiring of explosive hydroearhon engines wh ere theterminal tips are subjected to great strain.

A further object is to provide a terminal tip of improved constructionin which a spool is provided around which the bare wire may be wound,and a shank is provided with wings for clamping the insulated coveringof the wire to the tip toprevent the stripping of the covering from thewire.

.In the accompanying drawings, Figure 1 represents a portion of anelectric conduct lug-wire and the terminal tip to which it is securedintop plan. Fig. .2 is a bottom plan view of the same. Fig. 3 is a sideview. Fig. 4 is a )lan. view of the blank from which is forms one end ofthe spool, the shank, and the wings. Fig. 5 is a front view of the platewhich forms the other end of the spool. 6 is a side view of the same.Fig. 7 is a longitudinal vertical section through the terminal tip, andFi 8 is a lorwitudinal vertical sec tion throng i a modified form ofterminal tip.

The electric conducting-wire herein represented is shown as composed ofa core 1*, made up of a plurality of strands twisted togather and aninsulated coverirTgZ therefor. The terminal ti oom rises a spool aroundwhich the core 1 of t 0 wire lswound, a shank projecting from one of theend plates of the spool, and wings extended laterally from the shank. Inthe present instance'the back end plate 1 of the spool is provided witha shank 2, which shank has extended therefrom lateral wings 3 and 4. Ahole 5 formed in the shank 2. end plate 1 is provided with a central hol6 therethrough, .he front end plate is dented by 7, which end plate isprovided wi i a countersunk portion 8 and a central flaii ge 9, formingthe wall of a central hole 1.0 therethrough. The

end plate 7 is secured to the end )late l by inserting the llange 9through the role (5 and then upsetting the flange against the liar-k ofthe end plate 1. The countersunk portion u of the end plate 7 serves tospace the end plates of the spool a sufl'ioient distance apart to )ermitthe core 1* of the (701l(ll1(tl1l,L--l1'ti to .e wound around the spoolbetween the said end plates in the ta cred groove formed thereby. Thistapers groove serves to cause the end plates to snugly gri the wire. Toerrnit this to be done, the insu ated coverin 3* is stripped away fromthe core 1* of the wire the required distance. he end of the core 1* ispassed through the hole 5 in. the shank 2 andbent into engagement withthe back of the shank. The wins 3 and 4 are then wrapped around the insuated covering 2 of the wire for securin it to the shank and also toprevent the iurt er stri PlX'lg'Of the covering from. the core. T 1ehole through the s 001 permits the passage therethrough of ahiding-screw (not shown here in) for the purpose of securing theterminal tip to any required support.

In the form shown in Fig. 8 the front plate of the s 001 is formed bydrawing the material of t is back plateinto the desired shape, thusobviating the necessity of riveting the front plate to the hack plate,as in the other form shownl What I claim as my invention is* 1. Asheet-metal terminal tip for wires comprising two end plates rivetedtogether to form a spool around which the wire n'iay he wound, and ashank formed integral with one of the end plates, to which the wire maybe secured the said shank having a hole therein throu ;h which the endof the wire may be passer to more securely look the wire in position.
